Is the bassline on Adele's "Rolling in the Deep" same as RS's "Gimme Shelter"?

Can anyone tell me if the bassline on Adele's "Rolling in the Deep" has been lifted/sampled from The Rolling Stones' "Gimme Shelter"? Or, is it laid out musically similar to "Gimme Shelter"? To the ear, they spund very much alike. And if that is the case, would the Stones get royalties and wrtting credits for it?
